City parcel or county parcel: settle this before anything else
In Brooksville, two building desks in the same town both issue flatwork permits. Look your parcel up on the Hernando Property Appraiser site and check the Levy Code. CWBE means the City of Brooksville handles your permit. CWES means you're outside the city and the Hernando County Building Division handles it. Your tax-bill mailing address won't settle it. The levy code will.
Same story across the county lines. Inside Inverness city limits the city issues permits, not Citrus. Inside Dade City limits the city's Building Department does the work, not Pasco. Bushnell is the odd one: since April 1, 2025 Sumter runs permits for the city. Once you know which desk you're dealing with, the rest of this guide covers what a concrete permit in Hernando County or next door takes for a driveway, patio, slab, carport or pole barn pad.
What a concrete permit in Hernando County costs outside the city, and what's exempt
Here is how a concrete permit in Hernando County works for homes outside Brooksville city limits in 2026, from the Residential Building Permit Exemption List and the flat fees in Resolution 2026-037.
| Job | Permit? | County flat fee |
|---|---|---|
| Driveway slab, house to the right of way | Yes | $140 |
| Slab meant to carry walls, posts or any future vertical construction | Yes | $180 (slab) |
| Patio-style slab under 500 sq ft, non-structural, not in a flood zone | Exempt | None |
| Porch | Yes | $180 |
| Premanufactured carport (DBPR-approved, anchored) | Existing slab: no permit. New slab with footings: permit | $125 (carport) |
| Shed of 120 sq ft or less | Exempt | None |
| Shed over 120 and up to 288 sq ft | Existing slab: no permit. New slab with footings: permit | $140 if the storage building is 200 sq ft or less |
| Garage, detached or attached | Yes | $300 |
| Structural retaining wall | Yes | $180 |
| Ornamental garden wall under 48 inches, sand-set pavers, decorative curbing | Exempt | None |
Flat fees aren't the whole bill. The county adds DBPR, radon, unlicensed-contractor surcharge and technology fees, and zoning or another agency may charge its own. The resolution also lets the building official price a permit by job value when needed: $18.75 for the first $1,000 plus $6.25 for each added $1,000 up to $50,000. Since March 3, 2026 every new application goes through the county's Tyler portal. The old portal only tracks permits filed before that date.
Where the 500 sq ft patio exemption stops working
The exemption reads "Non-Structural Concrete Slabs (under 500 sq. ft.)" and the county adds that it is "specific to patio style slabs only." A 16 by 30 backyard patio (480 sq ft) fits. A 20 by 25 slab (500 sq ft) doesn't, because the rule says under 500, not 500 or less.
Three things knock a slab out of the exemption even when it's small:
- Future building. The list says any slab "poured with the intent for future vertical construction or structural support shall require a permit." A pad meant for a screen room, a shed, a carport or a pergola with posts falls under that sentence.
- Flood zone. None of Hernando's local exemptions apply on property inside a Special Flood Hazard Area, or on commercial property. The county sends owners to its Forerunner flood map to check the zone by address or parcel ID. Coastal lots around Hernando Beach and Weeki Wachee Gardens sit largely in AE and VE zones on FEMA's map, so check before you assume.
- Easements. Recorded easements along lot lines stay in force even when you see no pipes or poles. An accessory structure inside one needs a county easement vacation or encroachment approval plus written sign-off from every utility involved.
Exempt doesn't mean anything goes. Even where no permit is needed, the slab still has to meet the Florida Building Code, floodplain rules, land development rules and zoning. Our patio and porch page covers sizing a patio to stay under the line when that's the goal.
